Set assignee/reviewers, maybe based on commit message?

Would be great if I could generate a commit message like this:

Summary of changes

Reviewers: @name1 @name2

And have ghstack automatically add them as reviewers for the PR. Even better if there is an option to automatically assign the PR to me, with a separate Assign-to: flag in the message to override that behavior.

This would greatly improve the workflow of submitting and reviewing PRs for my team.

Yes I have also found myself wanting this. Setting labels would be good too
